Step-by-step explanation:
The standard resolution for digital elements intended for web design and on-screen display is 4) 72 ppi (pixels per inch).
For web design and on-screen display, a lower resolution of 72 ppi is generally used to optimize file sizes and loading speed on websites. This resolution is sufficient for viewing images on screens but may not be suitable for high-quality printouts. Higher resolutions like 150 ppi, 300 ppi, and 600 ppi are commonly used for printing purposes where more detail and clarity are required.
